Reliability Assessment with Energy Resources Distributed in a Medium Voltage Network

An approach is proposed to reduce the transgressions of the indicators that evaluate the quality of the product in sets containing class A4 irrigating consumers (2.3kV to 44kV), using the use of Energy Storage Systems - SAE, and photovoltaic solar generation through PhotoVoltaic Plants (UFV). The approach is based on the values of the indicators and the consumption in the feeders to determine the adequate sizing of the SAE and the UFV to be installed in strategic points of the Feeder (AL). A study is presented in a substation containing six feeders, which contains the largest number of irrigators in the concessionaire. For data validation, the Net Present Value method (VPL) and the Internal Rate of Return (TIR) are used, resulting in a positive value.
